It shouldn’t be a surprise given that Hiroaki Yura, Hiroki Kikuta, and Shihori will be guests for this year’s Otakon 2010. The trio will appear during the opening ceremonies where the three worked together in composing, producing, and rehearsing the theme song, titled “Shackles of Night” which will be performed during the ceremonies.

The music will accompany the opening animation which is done by Japanese studio Production I.G.
